Abstract
A base station capable of communicating with a user equipment (UE) includes a transceiver configured to transmit downlink signals containing first and second antenna numbers, first and second oversampling factors indicating respective oversampling rates in first and second dimensions for each beam group, first and second quantities of beams indicating respective quantities of beams in the first and second dimensions for each beam group, and first and second beam skip numbers indicating respective differences of leading beam indices of two adjacent beam groups in the first and second dimensions, receive uplink signals containing a plurality of precoding matrix indicators (PMIs) from the UE. Other embodiments including methods and UEs and methods are disclosed.
